2 Golf History Originated from a game played off the coast of ScotlandFirst played during the 15th centuryInfluenced by Kolven from Holland and Chole from BelgiumChanged from hitting pebbles to hitting golf balls

3 Objects in Motion Golf ball and club are only main objects in motionPeople do not move around a lotMain focus on golf ball and it’s flight

4 Average Speed Speeds may vary depending upon the player and golf clubSpeed = Distance/TimeSpeed = 175/8Speed = 22.22y/s

5 Acceleration Important because it determines the distance of the shotAcceleration is a change in speed or directionAccel. = Change in Velocity/TimeAccel. = 22.22/8Accel. = 2.78y/s/s

7 Newton’s 1st LawA body at rest stays at rest unless acted upon by an outside force.Golf ball doesn’t move until hit and doesn’t stop until air resistance, gravity, and friction stops it.A body in motion stays in motion unless acted upon by an outside force.

8 Newton’s 2nd LawExplains how force, mass, and acceleration are relatedForce equals mass times acceleration.Mass of the golf ball times acceleration of golf club equals distance ball will travel

9 Newton’s 3rd LawWhen the club hits the ball the club exerts a force on the ball, and the ball exerts a force on the clubFor every action there is an equal, opposite reaction.

10 Tip: Don’t hit the ball into the water.Forces of GolfForces: Gravity, friction, speed, velocity, momentum, and acceleration.His feet are a balanced force because the ground is pushing up with the same amount of force as his feet are pushing downHis club is an unbalanced force because the force exerted on the ball is greater than the force exerted on the clubBalanced ForceUnbalanced ForceTip: Don’t hit the ball into the water.

11 Weight Classes?Weight doesn’t really matter in this sport, however it’s helpful to be in shape

12 Friction Friction is a force which opposes motionFriction is undesirable when you don’t hit the ball far enough and want it to keep going but it stopsFriction is desirable when you want the ball to stop

13 The work equation is: Work = Force*DistanceWork is performed by simply walking a golf courseWork is also done by swinging a golf clubWork = 2*5798Work = 11,596 foot-poundsWork = 2*4Work = 8 foot-pounds

15 Machines In Golf? A golf club is a simple machineIt is a 3rd class lever

16 Kinetic-Potential EnergyThere is maximum potential energy at the top of the backswingPotential energy is converted into kinetic energy when the ball is hitThe maximum kinetic energy happens right before the ball is struck

17 Golf An Exercise?While it’s true golf is not the best exercise, it is still an exerciseThe typical person burns 396 calories playing golf for one hour

18 Golf On The Moon?If you were to play golf on the moon, the ball would travel a lot farther because the moon has 1/6 the gravity as on Earth.It would also require less effort, because there is less resistance as you are swinging.

19 Ways To Improve Your GameUnderstand how momentum, acceleration, and speed can improve your swingUnderstand how exerting a stronger force on the ball, while still controlling the shot will increase distancePractice, practice, practice
